Med Sci (Basel) 2019 Mar 17;7(3). Epub 2019 Mar 17.

Department of Pulmonary and Critical Care Medicine, Sentara Virginia Beach General Hospital, Virginia Beach, VA 23454, USA.

The latest data from the United States and Europe reveal that rare small intestine cancer is on the rise, with the number of cases having more than doubled over the past 40 years in the developed world. Mortality has grown at a slower pace, thanks to improvements in early diagnosis and treatment, as well as a shift in the etiology of neoplasms affecting the small intestine. Nevertheless, 5-year survival for small intestine adenocarcinomas has lingered at only 35%. Read More

Multimodality imaging of small bowel neoplasms.

Abdom Radiol (NY) 2019 Feb 26. Epub 2019 Feb 26.

Department of Radiology, Mayo Clinic, 4500 San Pablo Road, Jacksonville, FL, 32224, USA.

Although the small intestine accounts for over 90% of the surface area of the alimentary tract, tumors of the small intestine represent less than 5% of all gastrointestinal tract neoplasms. Common small bowel tumors typically are well evaluated with cross-sectional imaging modalities such as CT and MR, but accurate identification and differentiation can be challenging. Differentiating normal bowel from abnormal tumor depends on imaging modality and the particular technique. Read More

Uterine Endometrial Stromal Tumors With Limited Infiltration: First Report of a Case Series Indicating Potential for Malignant Behavior.

Int J Gynecol Pathol 2019 Feb 21. Epub 2019 Feb 21.

Department of Pathology, Belfast Health and Social Care Trust, Belfast, UK (M.M., W.G.M.).

The distinction between a uterine endometrial stromal nodule (ESN) and low-grade endometrial stromal sarcoma (LGESS) is based on the nature of the interface between the lesion and the surrounding myometrium and the presence or absence of vascular invasion. Most LGESS exhibit widespread irregular myometrial invasion with or without vascular invasion, whereas ESNs are well-circumscribed without vascular invasion. Tavassoli and Norris proposed that minor marginal irregularity (up to 3 protrusions, each <3 mm beyond the main mass) is allowable in an ESN and these criteria have been incorporated into the World Health Organization Classification.

Loss of BCL9/9l suppresses Wnt driven tumourigenesis in models that recapitulate human cancer.

Nat Commun 2019 02 13;10(1):723. Epub 2019 Feb 13.

Cancer Research UK Beatson Institute, Garscube Estate, Switchback Road, Glasgow, G61 1BD, UK.

Different thresholds of Wnt signalling are thought to drive stem cell maintenance, regeneration, differentiation and cancer. However, the principle that oncogenic Wnt signalling could be specifically targeted remains controversial. Here we examine the requirement of BCL9/9l, constituents of the Wnt-enhanceosome, for intestinal transformation following loss of the tumour suppressor APC. Read More

Lung Metastases in Patients with Well-Differentiated Gastroenteropancreatic Neuroendocrine Neoplasms: An Appraisal of the Validity of Thoracic Imaging Surveillance.

Neuroendocrinology 2019 Jan 23. Epub 2019 Jan 23.

The ARDEN NET Centre, European Neuroendocrine Tumour Society (ENETS) Centre of Excellence (CoE), University Hospitals Coventry and Warwickshire NHS Trust, Coventry, United Kingdom.

Background/aims: To evaluate the impact of lung metastases (LM) on overall survival (OS) in well-differentiated (WD) stage IV gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) patients along with developing surveillance strategies for thoracic imaging.

Methods: Thirty-four patients with LM, from 3 centres, were identified (22 small intestine/12 pancreatic; 17 grade 1/15 grade 2/2 of unknown grade). For comparison, we used 106 stage IV WD, grade 1 and 2 GEP-NEN patients with metastatic disease confined in the abdomen. Read More

Distinct immunological properties of the two histological subtypes of adenocarcinoma of the ampulla of Vater.

Cancer Immunol Immunother 2019 Mar 2;68(3):443-454. Epub 2019 Jan 2.

Division of Medical Oncology, Department of Internal Medicine, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, Republic of Korea.

Adenocarcinoma of the ampulla of Vater (AOV) is classified into intestinal type (IT) and pancreatobiliary type (PB); however, the immunological properties of these subtypes remain to be characterized. Here, we evaluated the clinical implications of PD-L1 expression and CD8 T lymphocyte density in adenocarcinomas of the AOV and their potential association with Yes-associated protein (YAP). We analyzed 123 adenocarcinoma-of-the-AOV patients who underwent surgical resection, and tumors were classified into IT or PB type. Read More

A case of malignant insulinoma responsive to somatostatin analogs treatment.

BMC Endocr Disord 2018 Dec 27;18(1):98. Epub 2018 Dec 27.

Endocrine Unit, Department of Experimental and Clinical Biomedical Sciences "Mario Serio", University of Florence, Careggi University Hospital, Florence, Italy.

Background: Insulinoma is a rare tumour representing 1-2% of all pancreatic neoplasms and it is malignant in only 10% of cases. Locoregional invasion or metastases define malignancy, whereas the dimension (> 2 cm), CK19 status, the tumor staging and grading (Ki67 > 2%), and the age of onset (> 50 years) can be considered elements of suspect.

Case Presentation: We describe the case of a 68-year-old man presenting symptoms compatible with hypoglycemia. Read More

Treatment dilemma for survivors of rituximab-induced bowel perforation in the setting of post-transplant lymphoproliferative disorder.

BMJ Case Rep 2018 Dec 13;11(1). Epub 2018 Dec 13.

Department of Oncology, Mount Sinai Health System, New York, New York, USA.

Posttransplant lymphoproliferative disorder (PTLD) is a recognised complication of solid and haematopoietic stem cell transplant. It consists of a heterogeneous group of lymphoid neoplasms that arises secondary to post-transplant immunosuppression. Although there is no definite standard of care for the optimal treatment for PTLD, rituximab, a monoclonal antibody, with and/or without chemotherapy (usually CHOP=cytoxan, doxorubicin, vincristine, prednisone) has become a routine part of the treatment of any CD20 (+) PTLD, with response rates similar to chemotherapy with decreased toxicity.
